In recent years, surface modification technology of powders has attracted more and more attention. Surface coating modification is one type of surface modification. Coating, refers to wrapping inorganic or organic matter on the surface of particles to achieve the purpose of modification.
Modification of calcium carbonate is very common in various industrial fields. So, why does calcium carbonate need to be modified?
Simply speaking, calcium carbonate without surface modification is often used as filler to reduce raw material costs, and its application areas and functions are subject to certain restrictions. While, after surface modification, calcium carbonate can transform from ordinary filler to modifier that improves properties and functions of products.
Qingdao Epic powder machinery Co., Ltd is a manufacturer specializing in the production of powder processing equipment. Our main products include: mills, e.g: kilang bola, kilang penggelek; classifiers, e.g: HTS air classifier, ITC air classifier; modifiers, e.g: pin-mill modifier, three-roter-mill modifier; and related auxiliary equipment, e.g: control cabinet, suction fan.
We have three types of coating equipment for the modification of calcium carbonate. They are: pin-mill modifier, three-rotor-mill modifier dan turbo-mill modifier.
① Pin-mill modifier
The modification efficiency of pin-mill modifier is currently the highest, It is suitable for large-scale continuous production. The two high-speed counter-rotating pins can disintegrate calcium powder and complete coating modification in the chamber.
② Three-rotor-mill modifier
Three-rotor-mill modifier is a very popular coating equipment at present. It consists of three rotors that rotate at high speed and interact with each other to achieve the purpose of modification of calcium powder.
③ Turbo-mill modifier
Turbo-mill modifier is also a commonly used powder modification equipment. It utilizes high-speed rotating impellers and airflow to achieve surface modification of calcium powder.
The three types of coating equipment mentioned above are all suitable for the modification of calcium carbonate. Customers can choose the suitable type according to actual needs.
If you have any needs or questions about modification equipment or other products, please contact our staff directly, we are always at your service.
